首次采用多元醇法在不同温度下合成了不同形貌的Cu2O粒子。扫描电子显微镜和透射电子显微镜表明，在140℃和160℃下得到的样品呈现核壳结构。X射线衍射仪测试表明，两种样品的结晶度均高于120℃下制备的样品。充放电实验和循环伏安(CV)结果表明，形貌和结晶度对Cu2O样品的电化学性能有重要影响。(C)2007年，爱思唯尔出版。
For the first time Cu2O particles with different morphologies are synthesized by adopting a polyol process performed at different temperatures. SEM and TEM show that the samples obtained at 140 and 160 degrees C present a core-shell structure. XRD measurements indicate that both samples exhibit better crystallinity compared with the samples obtained at 120 degrees C. Results from charge-discharge experiments and cyclic voltammograms (CV) reveal that morphology and crystallinity play important roles in determining the electrochemical performance Of Cu2O samples.
